' Specification describing a new and useful Improvement in WhiffletreeDraft-Eye, invented by EDWARD E. TOMPKINS, of Sing Sing, county ofWestchester, State of New York.

My invention has for its object to furnish an improved draft-eye forwhiffletrees, which shall be so constructed that the tug cannot come offaccidentally, and which shall at the same time be simple inconstruction, convenient in use, reliable in operation, inexpensive inmanufacture, and at the same time neat and light in appearance; and itconsists in the draft-eye constructed as hereinafter more fullydescribed.

A represents a screw, which is designed to be screwed into the end of ea whiffletree, B, as shown in Figs. 4, 6, and 7. Upon the outer end ofthe screw A is formed ahead, 0, which is elongated to form a neck orstem to receive the eye of a tug, D, as shown in Figs. 5 and 8. To theouter end of the neck or stem 0 is swiveled a cross-head or button, E,upon the side of which is formed a toe, F, which projects along and fitsupon the side of the neck or stem 0, as shown in Figs. 2, 3, 5, 6. Ifdesired, the toe F may be extended around the neck or stem 0 to form aneccentric sleeve, as shown in Figs. 7 and'S but I prefer theconstruction first described as being more sensitive to slight movementsof the tug. If desired, the stem 0 may extend entirely through theswiveled cross-head or button E, and may have a stationary cross-head,G, attached to or formed upon it as may be desired, as shown in Figs. 4,5,6, 7, 8.

In using the device the swiveled cross-head E is turned into line withthe eye of the tug I), and parallel with the stationary cross-head Gwhen used, and the tug-eye is passed over it. The pressure of the sidesof the tug-eye upon the toe or eccentric F, forces said toe into one orthe other end of said tug-eye, bringing the bottom or cross-head E atright angles with the length of the tug-eye, and keeping it there,however much the said tug may swing about, so that it will be impossiblefor the tug to become accidentally detached.

Having thus described my invention, I claim as new, and desire to secureby Letters Patent- I An article of manufacture, consisting of screw A,elongated head 0, neck 0, swiveled button E, and toe F, all constructedand put together as set forth.
